Common problems with installing and using electric push rods

The worm gear of the electric push rod has a simple structure and wears slowly during normal operation. If pre selection and post maintenance are required, some electric push rods can be used for five years or even more. Let's understand the selection of electric push rods and some issues that should be paid attention to during use.
The allowable torque, speed, and power of a screwdriver vary when lifting different loads. No matter the static load, dynamic load, or impact load, they should not exceed the allowable range. The wire should be checked according to the safety factor and the stroke should be used. Choose an electric push rod with sufficient capacity for the stability of the rod.
The worm gear of the electric push rod is usually made of tin bronze. Harden the matching worm material with 45 # steel to HRC4555, or harden 40Cr to HRC5055, and then grind it to a roughness of Ra0.8um using a worm grinder. During normal operation, the wear of the screw elevator is slow. If the wear rate is fast, please consider whether the selection is correct, whether the load is too large, the material of the worm gear, assembly quality, or usage environment.
The material of the worm gear elevator is non-ferrous metal. The worm gear and screw are driven by sliding friction, which generates more heat during operation, leading to thermal expansion between the parts and the elevator seal.
The gap is formed on the mating surface, and due to the increase in temperature, the lubricating oil becomes thin, which can easily cause leakage. There are four main reasons for this situation. One is the unreasonable combination of materials; The second is the unreasonable combination of materials. Secondly, the quality of the friction surface is poor. The third issue is the incorrect selection of lubricants. The fourth is the assembly quality and harsh usage environment.
